Oxidative bromination reaction using Cu2+-perfluorophthalocyanine-immobilized silica gel catalyst under mild reaction conditions
TL;DR: In this article, a simplified route has been applied for the grafting of copper(II) perfluorophthalocyanine complex onto functionalized silica gel, and the resulting organic-inorganic hybrid material is used as an efficient and recyclable catalyst for the regioselective oxidative bromination of various aromatic substrates using KBr/H2O2 as the reagents, affording high yields under mild conditions.

Cross-Dehydrogenative-Coupling of Alkoxybenzenes with Toluenes: Copper(II) Halide Mediated Tandem Halo/Benzylation of Arenes.
TL;DR: Preliminary mechanistic studies suggest that the in situ production of haloarenes followed by a copper-mediated coupling of a benzylic radical is operational.
